Templating C₆₀ on MoS₂ Nanosheets for 2D Hybrid van der Waals p–n Nanoheterojunctions

C 60 and single-layer MoS 2 nanocomposites were facilely prepared via a combined solvent transfer and surface deposition (STSD) method by templating C 60 aggregates on 2D MoS 2 nanosheets to construct hybrid van der Waals heterojunctions. The electronic property of the hybrid nanomaterials was investigated in a direct charge transport diode device configuration of ITO/C 60 –MoS 2 nanocomposites/Al; rewritable nonvolatile resistive switching with low SET/RESET voltage (∼3 V), high ON/OFF resistance ratio (∼4 × 10 3 ), and superior electrical bistability (>10 4 s) of a flash memory behavior was observed. This particular electrical property of C 60 –MoS 2 nanocomposites, not possessed by either C 60 or MoS 2 nanosheets, was supposed to be due to the efficiently established C 60 /MoS 2 p – n nanojunction, which controls the electron tunneling via junction barriers modulated by electric-field-induced polarization. Thus, our 2D templating method through STSD is promising to massively allocate van der Waals p – n heterojunctions in 2D nanocomposites, opening a window for important insights into the charge transport across the interface of organic/2D-semiconductors.
